What treatment uses chemicals to kill rapidly dividing cells, particularly cancerous cells?

Chemotherapy is a medical treatment specifically designed to target and kill rapidly dividing cells, which is a hallmark of cancerous cells. This treatment employs powerful chemicals that can interfere with the cancer cells' ability to grow and divide. The primary goal of chemotherapy is to reduce the number of cells in a tumor, help control the spread of cancer, and alleviate symptoms associated with the disease.

While a biopsy is a procedure used to obtain a tissue sample for diagnosis, it does not involve treatment. Antibiotic therapy is aimed at treating infections caused by bacteria and does not specifically target cancer cells. Cyst treatment refers to methods used to manage cysts, which are often benign and not related to the treatment of cancer.

Understanding how chemotherapy works and its role in cancer treatment is essential, as it provides insights into the broader category of cancer therapies and their mechanisms of action.
